The main types of waterproofing methods include cementitious waterproofing, liquid waterproofing membrane, bituminous coating, bituminous membrane, and polyurethane liquid membrane. Each method has specific applications and benefits depending on the project's requirements.

Cementitious waterproofing involves using a cement-based compound that forms a waterproof barrier. It is commonly used in areas like water tanks, basements, and swimming pools due to its easy application and durability.

Liquid waterproofing membrane is a type of coating that is applied as a liquid and cures to form a seamless, flexible, and durable membrane. It is ideal for flat roofs, balconies, and terraces, providing excellent protection against water infiltration.

Bituminous waterproofing offers excellent water resistance, durability, and flexibility. It is often used for roofing applications, underground structures, and retaining walls. There are two main types: bituminous coatings (or asphalt coatings) and bituminous membranes.

Polyurethane liquid membrane is highly elastic and durable, making it suitable for surfaces that are exposed to weathering, such as roofs and balconies. It provides a seamless, long-lasting waterproof barrier and is especially effective in areas with high UV exposure.

Key factors to consider include the type of structure, exposure to weather conditions, the area to be waterproofed, budget, and the specific requirements of the project. Consulting with a professional waterproofing service provider can help determine the most suitable method for your needs.
